White Papers and Case Studies

  1. Semi-Transparent Mirrors For Visually Dynamic Hospitality Displays
    4/27/2018

    Hotel, restaurant, and retail owners are increasingly using aesthetically pleasing high-performance semi-transparent mirrors to create a visually dynamic display/mirror combination. These mirrors are constructed with a display unit hidden behind the glass that is not visible until powered on. 

  2. “Dynamic” Deadfront Interface Panel Glass
    4/19/2018

    A “dynamic” deadfront panel is used to create a sleek, uncluttered user interface appearance, drawing attention to the “hidden” light up indicators as required. The icons or other alpha-numeric indicators are visible when backlit, and when unlit, a monochromatic streamlined look is achieved. Abrisa Technologies offers complete solutions for deadfront panel glass technologies including screen printed graphics, chemical strengthening or heat tempering, anti-scratch coatings, and more.

  3. Optical Monitoring System Improves Thin-Film Coating Accuracy
    3/14/2018

    In the past, a thin-film design software was used to help develop the coating, but the real challenge was in actually replicating the design thickness and the material indexes inside the coating chamber, without any errors. 

  4. New Tool Measures 4 Surface Appearance Quality Conditions Simultaneously
    1/18/2018

    If surface appearance quality is critical to your product, learn about a new manufacturing-friendly tool that allows you to establish numerical standards for and measure four conditions of surface quality: gloss, haze, image clarity, and BRDF including Canon’s new parameter “Scattering C20, C60.” 

  5. How To Select A Spherical Lens
    7/6/2016

    Optical systems use lenses to focus, collimate, expand, collect, and image light. Ranging from convex to concave, and bestform to aspheric, any lens selection must be made with the utmost consideration for its purpose as well as its required quality. This white paper delivers a review of singlet spherical lens shapes, and guidance on deciding the best lens characteristics for each application.

  6. Specifying Optical Filters for Sensor Applications
    7/1/2016

    Each sensor application has its own subtleties that need to be addressed in order to choose the appropriate optical filters for each sensing task. This application note discusses the critical parameters for bandpass filters that are to be used for sensor applications, including considerations on in-band transmission, band edge placement, and out-of-band blocking.

  8. Technical Note: Guide To Glass
    6/30/2016

    Guide to Glass provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties; Understanding light & color; glare reduction; and glass Strengthening methods using heat and chemicals.

  9. Specifying Wavefront Or Surface Error In Aspheres
    5/12/2016

    The optical quality of aspheric mirrors is commonly specified by their surface accuracy and reflected wavefront error. The surface error is the deviation of the surface from its perfect form, while the wavefront error is the deviation of the resulting reflected or transmitted wavefront from its perfect shape. It is often assumed that these tolerances are related to each other by a simple scale factor. However, that is not the case when it comes to aspheric mirrors. This application note compares surface accuracy measurements with wavefront error measurements, and provides an application example on using them in off-axis parabolas.

  10. Benefits Of Heat Tempering vs. Heat Strengthening Of Glass
    4/12/2016

    There are two types of heat-treated glass. Heat-strengthened glass is approximately two times stronger than annealed or untreated glass, while the tempered glass will be four times stronger and less likely to experience breakage through thermal shock. This application note presents the benefits and characteristics of each type of heat-treated glass.
